如何通过Ajax调用加载外部javascript

Question

我对Ajax完全是个新手。在我们的网站上，我们有一个购物车页面，在那里用户可以添加，删除和更改数量的项目使用ajax没有做整个页面加载购物车。我的问题是，每当用户更新他的购物车项目时，我需要触发一些第三方外部呼叫。

我有一个ajax调用，它调用jsp来计算脚本的参数。现在这个jsp包含了第三方外部脚本，据我所知需要单独启动。我正在将我的代码添加到下面，如果有人能帮助我，我将不胜感激

var callExternalUpdate = function(secure) {
    var ajaxParams = "secure=" + secure;
    ajax('POST',
        '/abc/my-ajax.jsp',
        ajaxParams, 
        function(r) {
            eval(r.responseText);
        },
        function(r) {
            //alert(r.responseText);
        }
    );
}

下面是my-ajax.jsp中的代码

<script type="text/javascript" src="http://www.mywebsite.com/js/criteo_ld_0.5.4.js" async="true"></script>
<script type="text/javascript">var CRITEO_CONF = [[{ 
    pageType: 'basket', 
    'Product IDs': [123], 
    'Prices': [10], 
    'Quantities': [1] 
    }], [6507,'ppr','us.','110',[[7721658, 7721659]],{'Product IDs':['i',1], 'Prices':['p',1], 'Quantities':['q',1]}]]; 
    if (typeof (CRITEO) != "undefined") { CRITEO.Load(false); }
</script>

我知道我会省略标签，因为我在javascript.But中使用了eval，如何调用外部javascript？

请帮帮忙。

Answer 1

让criteo_ld_0.5.4.js与您的页面一起加载，并让JSP页面只返回java脚本表达式的值，而不返回任何脚本标记。

var CRITEO_CONF = [[{ 
pageType: 'basket', 
'Product IDs': [123], 
'Prices': [10], 
'Quantities': [1] 
}], [6507,'ppr','us.','110',[[7721658, 7721659]],{'Product IDs':['i',1], 'Prices':['p',1], 'Quantities':['q',1]}]]; 
if (typeof (CRITEO) != "undefined") { CRITEO.Load(false); }
